AlM:To discuss the application of prism alternate cover test ( PACT) and perimeter strabismometry in strabismic operation.METHODS: A total of 145 patients with concomitant esotropia or exotropia, aging 2 ~ 50 years old, were included. They were examined by PACT and perimeter strabismometry before operation. The strabismic operations were performed, the orthotropia rate of postoperation was assessed.RESULTS:Using PACT and perimeter strabismometry, there was a significantly difference of deviating angle ( P<0. 05) in mild and severe strabismic group. But there was no significantly difference of deviating angle (P>0. 05) in moderate strabismic group. The functional cure rate of postoperation was respectively 70. 83%, 67. 01%; the clinical cure rate was 20. 84%, 24. 74%; invalid rate was 8. 33%, 8. 25% .CONCLUSlON: The application of PACT and perimeter strabismometry in strabismic operation design, referring to the eye axial length, this can be helpful of improving the cure rate postoperation and decreasing the danger of reopreation.

In order to construct generally efficient cell immortalization vector, pTP-hTERT, we modified the traditional piggyBac (PB) transposon using artificial synthesis, PCR and enzyme digestion. The modified vector contained the necessary transposon elements, a PB transposase expression cassette, a co-expression selectable element and a human telomerase reverse transcriptase (hTERT) expression cassette. The co-expression selectable element had two markers, enhanced green fluorescent protein (EGFP) gene and puromycin-resistance (Puro) gene, linked by porcine teschovirus-1 2A peptide (P2A). To validate the functionality of vector elements, we transfected pTP-hTERT into HEK293 cell, selected the positive cell clones and then conducted RT-PCR, Western blotting (WB) and Tail-PCR, methylene blue staining and statistic analysis on selected cells. The results of sequencing and cell culture show that the pTP-hTERT was constructed successfully and the positive cell could be selected by puromycin. The WB results, P2A cutting EGFP and Puro fusion protein with high efficiency, reflected the selectable element worked. The sequencing result of Tail-PCR confirmed the vector integrated into the genome through transposition. The results of methylene blue staining and statistic analysis indicated the clone of positive cells triggered by pTP-hTERT significantly increased (P < 0.01) compared with control group. The construction of pTP-hTERT provides an efficient tool for establishing immortalized cell lines and a demonstration for building other eukaryotic plasmids.

OBJECTIVETo observe and evaluate objectively the clinical effect of Guilong Tongluo Capsule (GTC) in treating chronic inflammatory demyelinating polyneuropathy (CIDP).

METHODSSixty CIDP patients were equally randomized into two groups. The treated group was administered with GTC and prednisone, while the control group with prednisone alone. Changes before and after 3-month treatment in terms of muscle force, functional and sensory disturbance of extremities, as well as scoring by Activity of Daily Living Scale (ADL) and electromyogram (EMG) for nerve conduction velocity were observed and compared.

RESULTSThe total effective rate gained in the treated group and the control group was 90.0% (27/30) and 70.0% (21/30) respectively, showing significant difference between them (chi2 = 14.82, P < 0.01). The improvement in the treated group was superior to the control group in muscle force of lower limb, motive and sensory function of extremities, ADL scores and motive function of ulnar nerve (P < 0.05, P < 0.01).

CONCLUSIONThe curative effect of GTC combined with prednisone in treating CIDP was better than that of prednisone alone.

Objective To study the relationship between self-esteem and childhood abuse, life events among male violent adolescent. Methods According to the modified overt aggression scale, juvenile delinquents were divided into violent group (n = 128 )and nonviolent group (n = 118 ). All the participants were investigated by Self-Esteem Scale (SES), Childhood Trauma Questionnaire-28 Item Short Form (CTQ-SF) and Adolescent SelfRating Life Events (ASLEC) and conducted correlation and regression analysis. Results ①Violent group had lower self-esteem scores ( 22.73 ± 3.30 ) than the nonviolent group ( 23.81 ± 3.30, P ＜ 0.05 ). Violent group had higher scores in physical abuse, sexual abuse, total life events, interpersonal relationship, punishment, and other (8.30 ±4.07, 7.23 ±2.26, 54.48 ±18.60, 10.09 ±3.84, 14.43 ±5.87, 4.93 ±3.15, 9.93 ±3.64), compared to the nonviolent group (7.27 ± 3.27, 6.60 ± 2.09, 45.40 ± 18.45, 8.42 ± 4.13, 11.07 ± 5.75, 3.66 ±2.81, 7.84 ±3.66, P＜0. 05). ②The self-esteem was significantly negative correlated with the childhood abuse and life events( r= -0. 143 ～ -0. 358, P＜ 0.01 ) among violent male adolescents. ③The physical abuse and punishment had significant prediction function of 15.6% on self-esteem. Conclusions Violent adolescents have low self-esteem, which is closely related to childhood abuse and adolescent life events.

Objective To study the effect of antiapoptosis factors PED/PEA-15 and XIAP on prostate cancer cells(PC-3)apoptosis.Methods The expressions of XIAP and PED/PEA-15 in prostate cancer cells(PC-3)were respectively assayed using the RT-PCR technique.XIAP and PED/ PEA-15 specific siRNA vectors were designed and constructed and then were transiently cotransfected into PC-3 cells under induction of liposome.The effects of siRNA vectors on PED/PEA-15 and XIAP transcription were assayed by RT-PCR technique,and the effect of XIAP and PED/PEA-15 on cancer cell apoptosis were determined by flow cytometry and microscope observation.Results PED/PEA- 15 and XIAP were both highly expressed in PC-3 cells.Enzyme digestion analysis and DNA sequencing confirmed that the PED/PEA-15 and XIAP-specific siRNA expression vectors were constructed successfully.The designed siRNA sequences of PED/PEA-15 and XIAP could specifically inhibit their transcription.The PC-3 cells which were cotransfected with PED/PEA-15 and XIAP- specific siRNA vectors were more sensitive to doxorubicin.The apoptosis rate of cotransfected cells was significantly increased.Conclusions PED/PEA-15 and XIAP might be involved in the development of prostate cancer.
